8 Claims.

The present invention relates to woven fabrics.

The principal object of this invention is to provide a woven fabric ofnovel and improved construction, which presents the appearance of cord.

Another object hereof is to provide a novel and improved woven fabric ofcord character, which is simple to manufacture, reasonably cheap incost, and particularly adaptable to be used in the manufacture of ladieshand bags, hats, shoes, upholstery and drapery materials and variousother articles.

Other objects and advantages, will become manifest, as this disclosureproceeds.

In the accompanying drawing, similar characters ofreference indicatecorresponding parts in all the views.

Fig. 1 is a pictorial representation of cloth which is the subject ofthis invention, with excess warp threads as yet untrimmed.

Fig. 2 shows the character of the weft threads employed in the making ofsaid cloth, shown magnified.

Fig. 3 is a magnified diagrammatic representation of a section takenalong the cloth.

Fig. 4 is a magnified View of a fragment of the cloth, shown partly insection.

In the drawing, the numeral l5 indicates generally a series of very finethreads, preferably of rayon-like character, constituting a warp of thefabric. For the weft, thread material of the nature indicated generallyby the numeral I6 is employed, which is commonly known as ratin yarn.Its body is such that its fibres are knotted loose in spots, orotherwise massed, making a wad-like or lump-like structure thereof atclose intervals along its length. It

usually includes a .loosely entwined thread thereabout. The enlarged orlump-like portions are indicated by the numeral l1, and the entwinedthread by [8.

In the ordinary weaving of fabrics, alternate warp threads as a unit,and their intermediates as a unit, are moveable so as to make adecussation or crossing known as a shed in which the weft is deposited,then said units are moved to cross in opposite direction, thus securingthe weft strand last deposited and forming a shed for the next depositof weft. Such manner of weaving is too well known to need furtherexplanation or any illustration. 1

To weave the fabric of this invention, ordinary loom means are employed,but the shed is changed after a number of ratin yarns I6,

l6, l6" and 16" are deposited in each shed the weft. curved-surfacedcomponents 20, appear as if I9. The shuttle of the loom either depositsthe four weft threads simultaneously at a single travel along a shed, orelse deposits a single thread as l6, by a back and forth motion twice ineach shed. The specific number of weft threads per shed here mentioned,is stated and shall be deemed only by way of example, and not as alimitation. Such number will vary depending upon the average distancebetween the wad portions l1, because the bunching of the several yarnsin each shed, will cause them as a set to form a cord-like structure;the irregular mass H of yarn l6, and ll of yarn l6", and 11'' of theyarn l6', will lie substantially forward of and in contact with oneanother filling in the space between a pair of successive masses ll ofyarn l6. Experience shows that any other aggregate formation of thelump-like portions of a" set of weft threads in any shed, is improbable,and that lumping at a spot in the fabric is very infrequent.

Such cord-like structure, formed by the bunching of the weft threads asa set in each shed, is of minutely uneven cross-section, about which thewarp threads I5 appear as if coiled and as a substantially thoroughcover therefor. Itis most desirable that the warp threads shall benumerous and substantially completely hide The successive cord-likecovered joined to one another as in cord work and the minute unevennessof their apparent seam lines 2|, presents a naturalnessto the fabric asif composed as ordinary cord work. Only the warp l5 constitutes the faceof the cloth of Fig. 1, which is of a bead-like cross-section along thewarp threads. The action of light upon the material due in part to theconvex formation of the surface of the cloth, lends a desirable beautyto the fabric.

This invention is capable of variousforms and applications withoutdeparting from the essential features herein disclosed. intended anddesired that the description herein shall be deemed illustrative and notrestrictive and that the patent shall cover all patentable noveltyherein disclosed; reference being had to the following claims ratherthan to the specific embodiment herein to indicate the scope of the It.is therefore threads being of comparatively large size and not twistedtogether, having lump-like portions spaced along their length; saidportions of the respective weft threads lying substantially contiguousto form a cord-like structure within each shed; the warp threadssubstantially covering the cord-like structures.

2. A fabric as in claim 1, wherein an equal number of weft threads arein each shed.

3. A fabric as. in claim 1, wherein the warp threads are of; light.reflecting material.

4. A fabric as in claim 1, wherein the warp threads are of a rayon-typematerial.

5. In a fabric, a warp consisting of a series of closely positionedthreads of small size, forming sheds and a weft consisting of at leastthree ratin threads not twisted together and being of comparativelylarge size in each shed, whereby a cord-like structure is formed in eachshed respectively; the warp threads substantially covering the cord-likestructures.

6. A fabric as in claim 5, wherein an equal number of weft threads arein each shed.

7. A fabric as in claim 5,. wherein the warp threads are of lightreflecting material.

8. A fabric as in claim 5, wherein the warp threads are of a rayon-typematerial.
